David Weddle met co-writer Bradley Thompson in an acting class, where they discovered both attended the USC School of Cinema. Years later, Thompson asked Weddle if he could adapt Weddle's play "Memoirs of an Awkward Lover" into a screenplay. Weddle agreed, but the two ended up collaborating on the project together. Nothing came of the adaptation.
After Star Trek: Deep Space Nine Executive Producer Ira Steven Behr read Weddle's book about filmmaker Sam Pekinpah, Weddle secured an invitation to pitch for the show and Thompson & Weddle collaborated on pitch ideas for the series.
Their first credited story on the series, was the fourth season episode "Rules of Engagement". The teleplay was written by Ronald D. Moore. Their first credited teleplay for Deep Space Nine was the fifth season episode, "The Assignment."
Thompson & Weddle continued to write for Deep Space Nine through its final season, writing two episodes from the final tightly-plotted nine-episode arc of the series.
